The Wrath of the Ancients
The four elemental bows of The Iron Dragon start, as on Der Eisendrache, from the Wrath of the Ancients, the plain bow. To earn it, feed the three dragon heads of the map: kill a zombie close to a head to wake it up, then keep killing zombies in front of it until it turns to stone and breaks. Guides count six to eight zombies per head. Once the three are fed, the bow waits on its altar in the main stairwell of the castle: from the bridge, go straight into the castle and turn right after the first room.

Dragon head of the bridge
On the gate at the entrance of the bridge, the first one met when leaving the spawn. Two doors stand between it and the spawn.

Dragon head of Mission Control
Above the fireplace of the church room of Der Eisendrache, which Not So Serious Gaming calls Mission Control: the same spot as on the original map.

The altar of the bow
In the main stairwell, a landmark of the map: the stairs climb from it to Double Tap, the orb room and the Pack-a-Punch, and go down to the crypt of the bows.
Dragon head of the courtyard
In a small courtyard on the left as you enter the castle, near the STG-44 wall buy and Electric Cherry. It hides in the shadows.
Every upgrade then follows the same pattern as on the original map: a broken arrow starts the quest, a few steps reforge it, and the reforged arrow goes on its pedestal in the crypt of the bows, under the castle, where zombie souls fill it until the elemental bow can be taken. Most steps are close to Der Eisendrache, with one or two changed per bow, as the Map Guide pinned on the Workshop page puts it. In co-op, any player can help with any step, whoever started the quest, and each player can carry up to three bows with Mule Kick.
The crypt of the bows
The underground room where the four pedestals stand, opposite the altar of the main quest. It is also the arena of the boss fight.
Splitting the souls
Zombies killed between two pedestals send their soul to both. DKnight 115 shows the trick to fill two bows at once, and Not So Serious Gaming saves the four souls steps for the end for this reason.
